TRACTOR WHEEL.

Specicaton of Letters Patent.

.Application filed August 4L, 1920; Serial No. V401,269.

Toell fit-,tom it may concern: 'y

Beit lrnown that l, ,EUGENE J. FARKAS, 'a present domain of Hungary,having applied tor and received my first papers 'tor naturalization inthe United States,

residing at Detroit, in the county of Wayne and State of Michigan, haveinvented a new and Wheel, of which thestollowing is a speciiication. A

rl` he object of vmy invention is to provlde simple, durable andinexpensive construction. t

A further object of my invention is to prowheel which may be used underordinary conditions of the soil and, 1n eou'ihination with such a tactorwheel, means for extending vthe lugs on the Wheel se that they muy, givethe necessary addi wherethe soil is extremely sott or sandy. i

il. further object of my' invention 1s to provide a tractor Wheel with.auxiliary lugs whereby such lugs may enter further into the' groundwhere greater traction is re* quired,

and to provide in combination with suoli lugs, means-:tor fastening themto the lugs ordinarily provided with the .tractor Wheel,A ln connectionwith the 'fastening means it muy lie mentioned that greet diiieulty beenexperienced in the past with detachable orextensihle lugs due to thefact up or cake with soil so that dillicult to regulate or change thewith which lam tait is very ft. further object of my invention is toproei'de a detachable lug which muyjbe secured to Ethe lugs usuallyprovided with the so' `that it may. he hlanked vfrom a strip ot' lineterial with a minimum amount ot Waste.

With these and other objects in view, my irnentim'i consists in thearrztngement, combination and construct-ion el the various parte otluy-improved device, as described claimed in my claims,

in which:

.liig'ure lrehoivs an elevation' fot my vim-` ed auxiliary lug,

useful improvement in e lractoia minimum amount of ialoni and, also toprovide such u lug` formed the rim 12 in position spaced from each iother are a plurality ot' lugs 13; these are the lixed or permanentlugsfof thewheel and areformed hy ,bolting or riveting one flange of anangle iron to the surface of the rim.y These lugs are preferably placedwith their longitudinal axis forming an i acute angle with a planethrough the axis ol the wheel. v 4 v My improved auxiliary detachablelug is designed to be secured to the fixed lugs 13,

and more especially to the outwardly exa tending flange of these lugs. lpreferably secure them 1n place by passing bolts 1l through the squaredopenings corresponding,r openings in Nuts urethen screwed on hold theauxiliary lugs from tive to the fixed lugs. These bolts le arepreferably formed with squared Shanks adjacent to their heads so thatthe nuts may be screwed up Without holding the head `with a Wrench dueto the engagement ofl the 15 and other the fixed lugs. the bolts 14 to`squared portions of the holt with the squared openings 15. '.llhe headsof the bolts are arcuate in 'cross section and do not have screw drivergrooves thereim so that as the lug slides into the `ground, there Willhelittle or no tendency for the dirt to catch on the hea-d of the boltand to pack around it. ln other words, the head oi' the bolt, is adaptedto allow the earth to slide past it as .far as possiblev thereby makingthat portion of" the -lugs what is termed, self-cleaning.

In connectionl with the shape of my iniproved lug,4it will he noted thatit iks cut oli' from a strip of material, eaehlug oeing the same inoutline on its'opposite edges, sothat the lug may be formed oysuccessive advances of .aLstrip-of materiel to position to "be`opsii-ated,upon foyathe same die. Itis Patented-May 23, i922.

`with the auxiliary lugsA movement rele-` `also so formed that inwardlyextending" ears 16 receive the squared openings 15, and thereby may betermed, fastening ears, and `outwardly extending ears 17 are formed atthe opposite edge of the lug. In this connection it will he noted that,due to the arrangement of theselout- Wardly and inwardly extending earsor portions, it is possiblev to form a lug having a useful Width whichis much greater than the quotient of the length oi the sti-ip divided bythe number of lugs formed there from. For example, in the use of anygiven strip, the useful width of the lugs may he six inches, yet it ispossible to secure three lugs to the foot instead of two lugs, due tothe shaping of the lug.

In the practical koperation of my improved device a tractor Wheel isformed, as de.

scribed, with the xed lugs 13 mounted thereon. If then it beadvisable,due to the conditions of the soil, to have lugs ot greater length on thetractor Wheel than the lugs 13, then the auxiliary lugsmay be bolted tothe lugs 13 by placing the auxiliary lug with the openings 15 alignedWith corresponding openings in the /lug 13, then punching the bolts 14through the openings, then screwing nuts on to the bolts to hold theauxiliary lugs in place.'

Among the many advantages of my mproved tractor wheel it may bementioned' that the Wheel is'v adapted, because of the auxiliary lugs,to travel through and have traction in soil which would be impassible tothe tractor having ordinary Wheels. it

is also possible to install the auxiliary lugs on the Wheels,

lground 4.engaginggfl one at a time, so that they i may be put in use atthe time when they/are Leichen most needed, namely, after the tractorhas been mired hy an unexpectedly soft piece of ground. ln thisconnection it will he noted that the holts are very readily tightened tohold the lugs in place due tothe fact that the head need not .he heldand it may also he mentionedthat Where the tractor has hccu mired thenit is only necessary to install enough of' the auxiliary liAG to pullthe tractor outI of the hole, A further :ulvair tage resides from thetact that the auxiliary lugs are so shaped that they may he punched outoi a continuous strip of material by a single die and that a largeamount ol uniterial is saved in proportion to the Width or' the lug bythe shaping of the edges thereof while the eticiency of the lug is notthereby impaired. l

Some changes may ne made in the arrangement and construction of thevarious parts of my improved device Withmit departing from the spirit ofthe invention therein audit is my intention to cover hy my claims suchchanges as may he reasonably included within the scope thereof.

l claim as my invention:

1. ln a traction Wheel, a. lug attached to the periphery ofthe Wheel, anauxiliary lug attached to saidl rst lug. having; fastening ears andtraction ears, the space between the fastening ears heilig ofsubstantialiyv the same size and shape as the tractionA ears.

2. A tractor wheel lug having one or more traction ears and two or morefastening ears, th distance between the fastening ears he ingsubstantially equal to the Width of the traction ears.
